Hi all,
I'm installing my Lift Pump and part of the process was cutting off the stock factory supply line fitting on the OEM lift pump.
908203

When installing the fuel tank and reattaching the lines, it says to reinstall the factory return line and supply line, but I cut off the factory supply line to install the bigger fitting. I guess I leave the original factory supply line from the truck disconnected? Rather be safe than sorry. I know under the hood I disconnect the original CP3 fuel supply line fitting.

Run a sump like the one below and you can pick if you want to return through your new fitting or return to the sump

Called FASS and what I assumed was correct. Just leave the factory supply line disconnected or remove it. I'm going to leave it there, but tape off the ends.
